Side by side
All 2025 reports of each operator, across every ship type. Change is against 2024 where the operator reported then.
| ZITON A/S | |
|---|---|
| Ships | 5 |
| CO₂ emitted | 29 kt |
| Fuel per mile | 329 kg/nm |
| Average speed | 6.1 kn |
| CO₂ at berth | 10.4% |
| Ships burning LNG | 0 |
| Main segment | Offshore |
Fuel per mile and speed depend on ship size and type; compare them within a segment below.
Segment by segment
Efficiency only compares within a ship type. Each row gives the CO₂ per transport work of an operator's typical (median) ship, and the bar sets it against the typical ship of the whole segment: to the left of the line it emits less CO₂ for the same transport work, to the right more.
Offshore
CO₂ per transport work (cargo) in g CO₂/t·nm · segment median 1,367

Verification and monitoring
Who verifies each operator's reports, and which MRV methods its ships use to measure fuel (share of reports).

ZITON A/S: ships furthest from their peers
Each ship's CO₂ per transport work against the median ship of its type and size band. +100% means the ship emits twice as much CO₂ for the same transport work as a typical ship of its size. Ro-pax ships show passenger figures, with freight underneath.
| Ship | IMO | Segment | CO₂ per transport work | Size-band median | vs median | Speed kn | CO₂ | Allowances |

30 of 5 reports shown. A high ratio can mean an older or faster-sailing ship, short trades with much time manoeuvring, or part-loaded voyages; it marks where to look first.
Notes
- Companies are ISM companies (Document of Compliance holders) as named in THETIS, usually the ship manager.
- Groups combine ISM companies matched on name and known ownership. If a company is in the wrong group, tell us at info@navalyze.com.
- Efficiency figures use full-year reports with fuel; totals include part-year reports.
- Euro figures use the EUA price set at the top of the page.
- Verifier names vary by entity and year (for example DNV AS and DNV Hellas); they are rolled up into one brand. A verifier's figures cover the ships whose 2025 report it verified.
